Why Did Trump Rename the Gulf of Mexico? Is the New Name Official?

Last updated 3 days ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

Hours after his second inauguration, President Donald Trump signed Executive Order 14172 directing the U.S. government to rename the Gulf of Mexico to the “Gulf of America.” The renaming triggered legal battles, diplomatic tensions, and operational complications.

Ten months later, the United States exists in a fractured geographic reality. Federal agencies call it the Gulf of America. Mexico rejects the name entirely. Your phone shows different labels depending on where you’re standing. And the Associated Press can’t enter the Oval Office because it refuses to use Trump’s name.

The Executive Order and Its Legal Foundation

The executive order, titled “Restoring Names That Honor American Greatness,” directed the Secretary of the Interior to rename the body of water bounded by Texas, Louisiana, Mississippi, Alabama, and Florida. The administration’s justification mixed economic and nationalistic arguments.

“We’re going to be changing the name of the Gulf of Mexico to the Gulf of America, which has a beautiful ring,” Trump said shortly after signing. “That covers a lot of territory… and it’s appropriate. We have a massive deficit with Mexico… and we help Mexico a lot.”

The order also reversed an Obama-era decision by restoring “Mount McKinley” as the official name for North America’s highest peak, which Obama had renamed “Denali” in 2015 to honor its traditional Alaska Native name.

Trump used a 1947 law establishing the U.S. Board on Geographic Names (BGN), which gives the Secretary of the Interior authority to resolve geographic naming disputes. Once the BGN makes a decision, all federal agencies must comply.

The executive order included an unusual provision: within seven days, agency heads had to review their BGN appointees and “consider replacing” them. This effectively allowed the administration to stack the Board with loyalists who would rubber-stamp the change.

The Secretary of the Interior issued Secretarial Order 3423, making the change official. The order was “effective immediately,” forcing federal agencies to begin a massive update of maps, databases, and documents.

The Federal Government’s “Big Scrub-Out”

Federal agencies scrambled to purge “Gulf of Mexico” from thousands of documents, a process observers called “the big scrub-out.”

NOAA’s Regulatory Overhaul

The National Oceanic and Atmospheric Administration faced the most complex task. On August 7, 2025, NOAA issued a final rule systematically replacing “Gulf of Mexico” with “Gulf of America” across regulations under six major federal laws, including the Coastal Zone Management Act, Marine Mammal Protection Act, and Endangered Species Act.

The amendments were meticulous, updating specific sections of the Code of Federal Regulations. But NOAA hit a legal wall: it couldn’t change the name of the “Gulf of Mexico Fishery Management Council” because that name appears in legislation. Only Congress can change statutory language.

The Gulf of Mexico Fishery Management Council now oversees Gulf of America regulations.

The National Weather Service began updating forecast zones, meaning mariners receiving weather alerts would hear warnings for the “Gulf of America” instead of the familiar “Gulf of Mexico.”

Coast Guard Navigation Updates

The Coast Guard moved quickly, publishing a final rule in March 2025 that invoked the “good cause” exception to skip public comment periods. The agency argued the change was merely “conforming” and had “no substantive impact on the public’s rights or obligations.”

But the operational reality proved messier. The Coast Guard had to revise the United States Coast Pilot navigation guide and update light lists describing aids to navigation. While physical buoys stayed in place, the digital metadata vital for GPS navigation required migration to the new name. This raised concerns about discrepancies between older paper charts still used as backups and new digital overlays.

Energy Industry Compliance

The Bureau of Ocean Energy Management (BOEM) and Bureau of Safety and Environmental Enforcement issued “Notice to Lessees” documents ordering all oil and gas operators to use “Gulf of America” in future filings and permit applications.

In November 2025, BOEM announced “Gulf of America OCS Oil and Gas Lease Sale 1.” Major energy companies like BP and Chevron updated their internal systems. Some reports indicate companies began retroactively referring to the 2010 Deepwater Horizon disaster as the “Gulf of America oil spill” to align with the administration’s narrative.

The Cost

A Congressional Budget Office estimate for a related bill projected federal costs under $500,000 for document updates through 2030. Some analysts questioned this estimate.

A pilot and veteran described the change as a “flaming dumpster fire of wasted effort,” noting that “Gulf of Mexico” is embedded in “charts, databases, textbooks, meteorology systems, environmental models, [and] international treaties.” Supporters argued the change ensured regulatory consistency.

Florida alone expected to spend hundreds of thousands updating road signage like “Gulf of Mexico Drive” and coastal markers.

The Constitutional Battle with the Press

The dispute extended beyond diplomacy to constitutional questions.

The Associated Press Refuses

The Associated Press declined to adopt “Gulf of America” in its reporting, citing its AP Stylebook. The AP’s guidance told journalists to “refer to it by its original name… while acknowledging the new name Trump has chosen.” The news organization argued that a name used for over 400 years and recognized internationally shouldn’t be changed for a global audience based on one country’s executive order.

The White House characterized this as defiance and revoked the AP’s press pool access, the rotating group of journalists granted close access to the President in the Oval Office and on Air Force One.

White House Press Secretary Karoline Leavitt defended the ban bluntly: “It is a privilege to cover this White House. Nobody has the right to go into the Oval Office… That’s an invitation that is given.” She directly linked it to the naming dispute: “It is a fact that the body of water off the coast of Louisiana is called the Gulf of America. And I’m not sure why news outlets don’t want to call it that.”

The Lawsuit

The AP sued in federal court, arguing the ban constituted viewpoint discrimination and retaliation in violation of the First Amendment.

The AP’s position: The White House press pool functions as a “designated public forum” for the accredited press. The government can’t exclude a specific outlet based on editorial policy. AP attorney Charles Tobin argued, “The First Amendment does not stop at the Oval Office door.”

The Justice Department’s counter: The Oval Office and Air Force One are “non-public forums”, essentially private spaces where the President has the same discretion to invite reporters as guests to a dinner party. “When the president invites reporters into the Oval Office, is he creating a First Amendment forum? The answer to that is clearly not,” DOJ attorney Yaakov Roth argued.

The Split Courts

In April 2025, U.S. District Judge Trevor McFadden (a Trump appointee) ruled for the AP, granting a preliminary injunction that restored access. He viewed the ban as “likely retaliation” that chilled protected speech.

The administration appealed to the D.C. Circuit Court of Appeals. A three-judge panel with two Trump appointees (Judges Katsas and Rao) stayed the injunction, reinstating the ban while the case proceeded.

During November 2025 oral arguments, Judge Neomi Rao expressed skepticism about forcing the President to admit specific reporters. “You would eventually need an injunction against the president for this to work, don’t you?” she asked, noting such orders are “extremely rare.”

As of November 2025, the AP remained barred from the pool. For the first time in modern history, America’s primary news wire couldn’t directly access the President due to a geographic naming dispute.

The Media Splits

Other news organizations had to choose sides, politicizing their style guides.

Conservative outlets like Fox News adopted “Gulf of America” immediately in chyrons, maps, and reporting. The Trump Organization’s ventures, including the newly launched “Trump Mobile,” naturally used the new name.

The New York Times, CNN, Reuters, The Washington Post, and The Wall Street Journal continued using “Gulf of Mexico”, typically adding context about the executive order.

Some outlets adopted neutral phrasing. The Christian Science Monitor and others began using “the Gulf” or “the Gulf Coast” to avoid taking a stance.

An American citizen’s understanding of their own geography now depends entirely on their news source. A Fox News weather report might warn of a storm in the “Gulf of America,” while a CNN app places the same storm in the “Gulf of Mexico.”

Tech Giants Create a Geographic “Splinternet”

Major technology companies responded by fracturing reality based on user location, a practice called “geofencing.”

Google Moves First

On February 10, 2025, Google updated its maps. Users accessing Google Maps from U.S. IP addresses saw “Gulf of America.” Users in Mexico saw “Gulf of Mexico” (Golfo de México). Users elsewhere saw both: “Gulf of Mexico (Gulf of America).”

Google defended this as a “longstanding practice of applying name changes when they have been updated in official government sources.”

Apple and Microsoft Follow

Apple initially resisted, leading to boycott campaigns by Trump supporters. But on February 11, one day after Google, Apple capitulated. U.S. users searching for “Gulf of America” were directed to the correct body of water, with labels updated accordingly.

Microsoft’s Bing Maps adopted the change quickly, reflecting the new federal name without significant public delay.

What This Means

The companies followed local government naming requirements. For users, the map on their phone is no longer a representation of physical reality but political reality as defined by their local government.

Mexico’s Fierce Rejection

Mexico characterized the renaming as cultural erasure. The Gulf of Mexico (Golfo de México) derives its name from the Mexica people (Aztecs) and has been in use since the 1550s.

Mexican President Claudia Sheinbaum responded with biting sarcasm. Standing before a world map at a press briefing, she proposed that if the U.S. could unilaterally rename the Gulf, perhaps Mexico should rename North America “Mexican America” (América Mexicana), citing historical documents from 1814 that used the term.

Beyond rhetoric, Mexico formally rejected the name change. Sheinbaum reiterated that U.S. sovereignty extends only 12 nautical miles from its coast. The U.S. has no authority to rename international waters.

After Google adopted the name for U.S. users, Sheinbaum announced a lawsuit against the company, arguing it was complicit in violating Mexico’s cultural sovereignty and misrepresenting international territory.

The International Community Refuses

The International Hydrographic Organization (IHO), based in Monaco, publishes the authoritative guide to maritime names used for navigation and international charts. The IHO operates by consensus among member states.

Since Mexico vehemently opposed the change, the IHO refused to adopt “Gulf of America.” As of November 2025, the IHO continued recognizing the body solely as the “Gulf of Mexico.”

This created a permanent split in maritime law. For all international navigation, admiralty law, and global shipping, the “Gulf of America” doesn’t exist. It’s a region recognized only in U.S. federal documents and U.S.-based smartphone apps.

The United Kingdom and other major maritime powers also declined to recognize the new name, citing common usage across the English-speaking world.

States Pick Sides

“Gulf of America Day”

To cement the rebranding, Trump proclaimed February 9, 2025, as “Gulf of America Day.” He signed the proclamation aboard Air Force One while flying over the Gulf to Super Bowl LIX in New Orleans, maximizing visibility for millions of viewers.

The proclamation described the day as a time to “come together and commemorate this momentous occasion” and “restore American pride.”

But polling in February 2025 indicated most Americans opposed the change, viewing it as unnecessary or confusing. Protests erupted in Washington D.C. and other cities, with demonstrators linking the name change to broader grievances about environmental deregulation.

Florida and Texas Act

Republican governors moved quickly to align their states with federal reality.

Florida Governor Ron DeSantis immediately ordered state agencies to adopt the new name. The Florida legislature filed bills, such as SB 608, to amend Florida Statutes. This bill proposed replacing “Gulf of Mexico” with “Gulf of America” in hundreds of specific statutes, from tourist development taxes to coastal construction control lines.

The bill’s preamble stated: “WHEREAS, on January 20, 2025, President Donald J. Trump issued Executive Order Number 14172… the Legislature intends to reflect this name change in the Florida Statutes.”

In Texas, the Senate passed SB 1717, formally renaming the Gulf on state maps and documents. The bill declared the title “Gulf of Mexico” to be “inaccurate and outdated.”

Legal Complications

These state laws created headaches for property owners. Real estate deeds often describe property boundaries referencing the “mean high-water line of the Gulf of Mexico.” Legal experts raised concerns about whether deeds would need reformation or if “Gulf of America” would be legally recognized as the successor.

Town attorneys in coastal municipalities like Longboat Key expressed confusion over whether local ordinances required spending municipal funds on new signage.

Economic Disruption

Shipping and Logistics

The maritime industry operates on precision. Ambiguity in location names creates liability. While the Coast Guard updated its local pilots, the divergence between U.S. and international charts raised insurance concerns.

Global supply chains rely on standardized location codes (UN/LOCODE). The unilateral U.S. change forced software providers to patch systems to recognize “Gulf of America” as a valid alias, adding friction and cost.

If a vessel insured under a policy referencing the “Gulf of Mexico” runs aground in a federally designated “Gulf of America,” insurers could theoretically dispute claims based on geographic discrepancies. While no such cases had been litigated by late 2025, the risk forced shipping companies to seek policy clarifications.

Tourism and Business

Local businesses faced branding crises. Hotels and restaurants with “Gulf of Mexico” in their names had to decide whether to rebrand and risk alienating traditional customers or stick with the old name and potentially offend Trump supporters.

Souvenir shops on Florida’s St. Armands Circle began stocking “Gulf of America” merchandise almost immediately, capitalizing on the political novelty.

Scientists Caught in the Middle

The scientific community faced a data management nightmare. Decades of climate data, hurricane tracks, and marine biology research are indexed under “Gulf of Mexico.” The forced switch to “Gulf of America” in federal databases created a “break” in the data record. Researchers now have to query two different terms to get a complete picture.

High-impact international journals like Nature and Science adhere to IHO standards and reject “Gulf of America” terminology. This places U.S. federal researchers in a bind: they must use “Gulf of America” in internal reports to satisfy agency bosses but translate it back to “Gulf of Mexico” to get published in credible journals.

The Nature Conservancy’s Contortion

Non-profit organizations dependent on federal funding faced an existential threat. The Nature Conservancy (TNC), with over $156 million in federal grants including $45 million from NOAA, couldn’t afford to alienate the administration.

TNC announced a carefully worded policy: “To ensure our programs continue, in accordance with clear directives from federal agencies… TNC is required to refer to its programs in the Gulf of Mexico in U.S. territorial waters as ‘Gulf of America.’ We continue to refer to our programs occurring outside of U.S. territorial waters… as ‘Gulf of Mexico’.”

This split, using one name for water near the beach and another for deep sea, shows the compliance requirements of the executive order. It forced scientific organizations to adopt political nomenclature as a condition of business, complicating research where naming consistency is vital for data integrity.

Status as of November 2025

By November 2025, “Gulf of America” had established itself as a fact of American federal life, despite international rejection and domestic opposition.

Table 1: Who Uses “Gulf of America” (November 2025)

The renaming demonstrated that a President can effectively rewrite the map for the federal government and its contractors through administrative mechanisms. It also revealed the willingness of tech giants to fracture truth to comply with local jurisdictions.

But international resistance held firm. The press, led by the AP, engaged in a high-stakes constitutional battle to resist compelled language, fracturing the media landscape.

The “Gulf of America” exists as a legal fact in the U.S. federal register and a digital fact on American smartphones. But it remains a fiction in international law and global science. Governments can change names on a map, but they can’t easily erase centuries of history or global consensus. The water remains the same, but the lens through which America views it has been profoundly distorted.
